Product Description

The ARP 256-4301 Head Stud Kit is engineered specifically for the 2013 and newer Ford 5.0 L Coyote V8 (M11 block), which uses 11 mm head studs. This kit replaces the factory torque-to-yield bolts with strong, reusable ARP2000 alloy studs to significantly improve head clamping force and reliability in high-performance or boosted applications.

Installation involves cleaning and chasing the block threads, installing the studs by hand, and then using the included parallel washers and 12-point nuts. Using ARP's recommended lubricant and torque sequence (35 → 70 → 100 ft-lbs) ensures consistent preload and optimal sealing. This head stud solution is ideal for tuned, forced-induction, or high-RPM Coyote builds where head lift or gasket failure may be a concern.
